AC problem (blower not working) code 13 - Toyota 4Runner Forum

Hello, after using the AC for a while it stops working (blower not working) for a few minutes and the it comes back usually around 10-20 min the climate unit shows code 13 (circuit on evaporator sensor), the blower works fine if I short the relay terminals, my theory is that the condensation is shorting the mentioned sensor and prevents the blower from running, any advice?

Check evap drain hose for clog, does water puddle under truck with AC running ? a place to start.

It seems to be draining properly, I'll use a metal wire later to confirm that it is unclogged

Next. The evap housing has fan resistor bank mounted to it removing it gives you a 2" x 4" openig to view Evap condition cleaning probably needed.

EVAP was cleaned recently, tech says the relay is working fine however it is not getting the signal from the computer or whichever module controls de AC blower activation
